Cooling Performance:

Although performance of the stock intercooler is good, it is just good for stock boost level. At boost 1.2k (GT570 Kit, GT600 Kit), temperature of compressed air will be increased. (Cause: Since stock core size is not enough for the flow capacity of stock turbochargers.) To improve cooling performance, larger core is required. After performance tests, if the core size is just slightly larger, there is not so much performance improvement. To achieve great performance enhancement, the large size (Size: 400x260x65) & thin core was selected.

Affection to water temperature:

Large capacity core tends to affect to air flow for radiator. With the thin core, air flow speed to radiator will be increased. During tests at Sendai Highland Circuit and Fuji Speedway by a professional racing driver, increasing of water temperature was the same level as stock system.

Special large carbon air guide:

The shape of the air guide fits to the core size. Induction air flow goes through efficiently to the core that enhances cooling performance. The side air guide plate guides air to radiator as well.
(The carbon pattern is mat twill weave cloth.)

HKS R35 Intercooler Kit Features:

• Lightweight: Intercooler unit is lighter than stock. It reduces weight of overhang.
• Pressure Loss: To prevent pressure loss due to the thin core, the new inner fin design will minimize pressure loss.
• Installation time: About 8 – 10 hours
• Kit parts: Intercooler assy, Air guide, Intercooler pipe, Silicon hose, Hose band, Bracket, Bolt & nut.
• Required tool: Nut cutter
• Required modification: Modification of air guide in front of stock radiator core support. Bending air conditioner pipe.
